The reference D compiler (dmd) makes builds for i386 and x86_64 Windows, OSX,
Linux and BSD, and extern C binding support is present in the library.
So no it shouldn't be difficult.
If .minfo section doesn't translate well to Mach-O however, shared library
support would need some work.
Would adding/finishing off ports be fine during stage 3?
